New feature
Description:
Add new "block tracker" data structure to library, for tracking blocks of
bytes in a file. Block trackers will be used to keep track of the blocks
belonging to the soon-to-be-implemented "segmented heap" which is designed to
replace the current local & global heaps (starting with the local heap).
Block trackers will also keep track of the free space in the segmented heap
and someday could be used to track the free space in the entire HDF5 file.
They are implemented as a small header of information to cache the state
of the blocks (max & min sizes of blocks tracked, etc.) and the records of
the blocks themselves are stored in a v2 B-tree.
Platforms tested:
FreeBSD 4.11 (sleipnir)
Solaris 2.9 (shanti)
h5committest

New feature & code cleanup
Description:
Change some references from 'keys' to 'records', which is more correct for
this implementation.
Added feature to allow preemptive 3 node record redistributions (for leaves
only currently)
Added feature to perform preemptive 3->4 node splits (for leaves only
currently)
Platforms tested:
FreeBSD 4.11 (sleipnir) w/parallel
Solaris 2.9 (shanti) w/purify
Too minor to require h5committest

New feature
Description:
Expand v2 B-tree code to support splitting the root node when enough
records are inserted and move metadata cache callbacks into their own source
file.
Platforms tested:
FreeBSD 4.11 (sleipnir) w/parallel
Too minor for h5committest

New feature
Description:
Add basic code for new B-tree implementation. They don't do much yet,
aren't hooked up to anything yet and the format may change, but I'd like to
start getting them into the daily tests.

FreeBSD 4.11 (sleipnir) w/parallel
